Tia Hellebaut (; born 16 February 1978 in Antwerp) is a retired Belgian track and field athlete, as well as a chemist, who started out in her sports career in the heptathlon, and afterwards specialized in the high jump event. She has cleared 2.05 metres both indoors and outdoors. Hellebaut was the 2008 Olympic champion in the high jump. She was previously the European Champion in 2006 and then the European Indoor Champion in 2007. She won the gold medal in the pentathlon at the 2008 IAAF World Indoor Championships. In addition to these medals, she has participated at the World Championships in Athletics on four occasions. She held the Belgian records indoor long jump and indoor pentathlon until they were broken by Nafissatou Thiam and still holds the Belgian record in both indoors and outdoors high jump. Career Hellebaut started as a professional athlete with Atletiek Vlaanderen in the period from 2001 to October 2005. From 1 November 2006 she again became a professional athlete, this time at Bloso. During her most successful period, Hellebaut was trained by her partner, Wim Vandeven, at her club, Atletica 84. At the 2006 European Championships and 2007 Indoor European Championships Hellebaut won the gold medal in high jump. The 2006 victory became especially notable, when just a couple of minutes later her close friend and compatriot Kim Gevaert completed a historical sprint double. The images of both athletes celebrating their victory together, wrapped in a national flag, became part of Belgian sports history. In 2007 Hellebaut set the then fourth best pentathlon score of all time, but chose not to contest the European Indoor Championships because of illness, choosing instead to compete only in the high jump, which she later won. Most of the remainder of her 2007 high jump season was hampered by an ankle injury. A shoulder injury, which made it difficult for her to throw the javelin, ended her career in heptathlon around this time. For the 2008 indoor season, Hellebaut returned her focus to multi-events and became world champion of pentathlon at the World Indoor Championships in Valencia, where she set a record for the best high jump result in a women's multi-event competition, clearing 1.99 m. At the 2008 Summer Olympics, held in Beijing, Hellebaut reached her pinnacle thus far by winning the gold medal in the high jump, ahead of the favorite, Blanka Vlašić of Croatia,
